Effective emitting temperature
WebTools. The effective temperature of an astronomical body like a star or a planet is the temperature of a black body that would emit the same total amount of electromagnetic radiation. [1] Effective temperature is often used as an estimate of a body's surface temperature when the body's emissivity curve (as a function of wavelength) is not known. WebMay 29, 2024 · In situ PL at high temperatures also correlates with the intrinsic quality of the semiconductor lattice itself because PL emission is typically affected by electronically-effective defects, such as radiative and non-radiative recombination centers in the semiconductor [1,5]. Defect monitoring at high temperatures is a new quality in this …
